2 Technical Specifications Model: Air pressure: PSI Nozzle diameter: 1.4 mm Type of feed: Gravity Air consumption: 5 CFM Pattern width: 7-1/2" (190 mm) Paint capacity: 3.5 oz Coating will be light at this point Coating will be heavy at this point Coating should be even and wet when spraying Start stroke Pull trigger Release trigger End of stroke Incorrect method Correct method Operation 1. Suggested air pressure is PSI 2. Recommended paint viscosity differs according to paint properties and painting conditions. 3. Use the lowest possible fluid output that produces an adequate paint coverage. Finer atomization leads to a better finish. 4. Maintain a distance of 6-8" from the gun to the workpiece. 5. The gun should be held so that it is perpendicular to the surface of the workpiece at all times. Move the gun in a straight and horizontal line. Arcing the gun results in an uneven paint finish.

3 Maintenance 1. Pour remaining paint into another container and then clean paint passage and air cap. Spray a small amount of thinner to clean paint passages. Incomplete cleaning will cause adverse pattern shapes and particles to appear on your work. Promptly clean components after use. 2. Clean other sections with a brush and cloth soaked with thinner. 3. Clean paint passages fully before disassembly. 4. Remove the fluid nozzle after removing the fluid needle set or while keeping fluid needle pulled in order to protect seat section. 5. While keeping fluid needle set inserted, tighten fluid needle packing set by hand. Then tighten gradually with a wrench. Adjust the packing set while pulling the trigger and watching the movement of the fluid needle set since over-tightening will strip the thread, causing leakage. 6. Turn the spread adjustment knob counterclockwise to fully open it, then tighten the spread adjustment guide into the gun body.

5 Troubleshooting Symptom Intermittent spray Pattern arched Problem Presence of air in the paint circuit Material residue in the holes obstructs the passage of material The nozzle is dirty or malfunctioning The atomization cap is dirty or damaged Solution Tighten the nozzle using the wrench provided. Make sure that the tank is not empty. Check that the connecting hole is not obstructed. Tighten the gland screw or replace the gasket if worn Submerge the head in solvent Clean and open all closed holes with a jet of compressed air or a toothpick. Do not use pointed metal objects, or you may deform the hole of the head part. Uneven pattern The center of the pattern is too narrow Material builds up on the outside of fluid nozzle tip or center hole or partially clogged nozzle orifice. Loose fluid nozzle Atomization of air pressure is too high Material too thin Clean the head and the nozzle Make sure that the centering between the two is precise Check that the tip of the pin is not ruined Replace the nozzle and the head Reduce the quantity of air and increase the flow of paint. Poor atomization. Spray concentrated into the centre The flow of paint is greater than the pressure and quantity of air supplied. Clean the head and the nozzle Make sure that the paint is not too dense and dilute if necessary Little to no paint output Fluid passage is clogged with dirt Air holes in the cover are blocked Fluid needle stroke is too short Remove obstructions Adjust fluid needle stroke
